Is it possible to config UCS STP priority in "Switch mode" ?

I want to config STP Priority for UCS in Switch mode (Default is 32768 + VLANID).
How can I do that ? please advice.
Thank you

• You cannot configure Spanning Tree Protocol parameters, such as bridge priority and hello timers.
Ethernet Switching Mode
The Ethernet switching mode determines the way that the fabric interconnect behaves as a switching device between the servers and the network. The fabric interconnect operates in either of the following Ethernet switching modes:
• Switch mode
• End-Host Mode
Switch Mode
Switch mode is the traditional Ethernet switching mode. Use switch mode when the fabric interconnect is directly connected to a router, or when Layer 3 aggregation or a VLAN in a box is used upstream (Figure 32). Switch mode has the following attributes:
• The fabric interconnects run Spanning Tree Protocol with connected external switches to avoid forwarding loops; broadcast and multicast packets are handled in the traditional way.
• The fabric interconnects run Per-VLAN Spanning Tree Plus (PVST+), which cannot be changed to another Spanning Tree Protocol such as Multiple Spanning Tree (MST).
• You cannot configure Spanning Tree Protocol parameters, such as bridge priority and hello timers.
• MAC address learning and aging are enabled on both the server links and the uplinks, so that the switch operates like a typical Layer 2 switch.
• Some uplinks connected to external switches may be blocked by spanning-tree rules.
Also remember that you are limited to the options presented to you via the CLI and GUI. They should have the same capabilities. If you do not see an option for configuring spantree priortiy, changing the value is not supported.

UCS Fabric Interconnect-switch mode

Hi
Can I connect my old HP server with DAS(to be used as a backup server) to a UCS FI operating in switch-mode-I guess I would need to connect the server to a network ports?

As of UCSM version 2.0 you no longer need "switch mode" to directly connect storage devices. You can set devices as Appliance ports. There's a wealth of community posts on setting this up. Pre 2.0 you would need switch mode, which gets really messy - you're far better directly connecting storage with Appliance ports on 2.0 or later.
As Eric mentioned, we only support Netapp & EMC devices for direct connect.
Please see the Storage Interop matrix for more detail.

That being said, it doesn't mean it will not work, just that TAC would not be able to assist if you ran into issues.

Is it possible to use UCS Blade Servers in ACE Load Balancing

Hi all ,
Is it possible to use UCS Blade Servers in ACE Load Balancing ?? Please note that UCS Blade Servers are not connected directly to 6500 Switch where ACE Module installed .i am expecting a good suggestion from whether ACE or Switching Expert
Thanks in advance
Sanjeevi

There is nothing that would prevent you from loadbalancing the applications that run on UCS servers. ACE can loadbalance applications that are directly L2 attached (bridged or routed mode) or even servers that are multiple hops L3 hops away using one-armed mode with source nat. The key to this is that the return traffic from the server needs to make it back to the ACE.

Is it possible to config RAC in laptop(one PC)?

Hi,
I have never configed RAC before,and I want to do some test about RAC.
Is it possible to config RAC in my PC (windows xp with one hard disk)?
Thanks

If you want to learn how it works, then use the link to Howard's site (Dizwell) that others have provided.
Just a reminder though - it is not valid if you want to test what does and does not work, or check performance, or see proper admin techniques, or ...
For that - if you are in the United States or western Canada, look at http://www.psoug.org

Cisco UCS an McData SAN Switch

Hallo zusammen,
wir versuchen eine Verbindung zwischen ESX auf einem UCS und einem NetApp Metrocluster herzustellen. SAN Infrastruktur basiert auf McData SAN Switchen.
In der Vergangenheit habe ich die komplette Infratruktur mit HP/Brocade SAN Switchen administriert ohne Probleme. Hier waren keine speziellen Einstellungen notwendig. WWN Pools und vHBA und die Verbindung stand.
Der SAN Admin meinte NPV sei auf dem Port aktiviert und NPIV wird unterstützt. Er sieht auch meine WWPNs und hat das Zoning am SAN konfiguriert. Leider sehen unsere ESX Server keine präsentierte LUN.
Für Tipps und Infos zur notwendigen Konfiguration wäre ich sehr dankbar. vSphere Umgebung läuft auf 5.5, UCS auf 2.1. Ich habe bereits alle Einstellungen unter UCS getestet. Ich habe auch ein bisschen mit den VSANs gespielt, was aber in der Vergangenheit nie notwendig war. FIs laufen im End Host Mode. ESX Rescan zeigt keine Pfade oder Target, LIP hat auch keinerlei Änderungen gebracht.
Da ich auf die SAN Konfiguration keinen Zugriff habe möchte ich zunächst sicher gehen, dass ich am UCS nichts vergessen habe. Switching Mode sollte kein Thema sein.
Viele Grüße
Bastian

Is it possible to use e.getsource with a switch statement?

Is it possible to use e.getsource for a switch statement? I keep getting an error, which I understand. I'm just not sure if it can be done by using another method or casting e.getsource to something. Any ideas? Thanks!
     public void actionPerformed(ActionEvent e)
          switch(e.getSource())
               //buttons 0 - 6
               case buttons[0]:
                    Master_Clock.tickPos();
                    break;
               case buttons[1]:
                    Master_Clock.tockPos();
                    break;
               case buttons[2]:
                    Master_Clock.reset();
                    break;
               case buttons[3]:
                    Master_Clock.tickNeg();
                    break;
               case buttons[4]:
                    Master_Clock.tockNeg();
                    break;
               case buttons[5]:
                    Master_Clock.dayPos();
                    break;
        }

Using the same actionPerformed method for all the buttons is an obsolete technique.
Use a seperate object implementing ActionListener with each button.
There's a lot to be said for using Action objects, which you can also connect to key presses menu items and so on.
Typically you create objects using the anonymous class technique. You'd do something like:
Action tickAction = new AbstractAction("Tick") { // create anonymous action
   public void actionPerformed(ActionEvent e) {
      MasterClock.tickPos();
JButton tickButton = new JButton(tickAction);

Possibility to run 9iAS for OCS in clustered mode
Hi,
we're using two nodes of 9iAS in two data centers. We've been told that it isn't possible to add the 9iAS to a 9iAS cluster. Does anybody has experience to use two nodes of 9iAS of OCS2 as cluster with load balancing and automatic configuration deployment functionality?
Any help would be welcomed...
Kind regards,

You can use RAC for the databases but the infrastructure is only supported with HA CFC (Cold failover Cluster). You can look at the document for this in this location.

Is it possible for skype to wake Mac from sleep mode?

Does anyone know if it is possible for skype to wake Mac from sleep mode?

Sadly there is nothing in Skypes Code fot it. In fact, Skype for Mac, is one of the most Vanilla versions out. Windows Version has 5x-10x the user functionality. Since Microflops buy into Skype, Mac versions will continue to be second rate on purpose, but be thankful, if Microflop was there from teh beginning, they woudl have banned a Mac version, just like they do in their higher tier games.

What are the CE500 STP priority settings? Help

Hi All,
Anyone knew the default values of the STP of CE500 series switches? I am afraid when I attached the switch to the network it will become the root switch. Need help in determining the bridge priority, path cost , etc. necessary for STP compliance. THanks!

STP default settings cant be changed on CE500.Only default settings are allowed.Option is add or delete a STP for a vlan.Instead change the priority accordingly so that C500 doesnt become a root switch.

Question about STP Priority & Cost

Hi All,
I would like to know what kind of effect could occurs when changing the following on PVST layer 2 Switches:-
1- Vlan port Priority.
2- Vlan root cost.
Appreciate any feedback,
thank you,

STP decisions are based on the following in descending order:
1. Bridge ID - this is priority + MAC
2. Root Cost - added inwards
3. Sender bridge ID -
4. Port ID - the first 6 bits of which are priority.
For all of the above, lower values are better. Root Cost is second in the decision.
Thanks.

On RT it's possible to have 2 Differents Priority VI call same Sub vi

As NI documentation precise, I implement 2 Vi's for my RT application
the first the highest priority handle all the critical tasks
the second manage the non critical and the dialog with a server
All works enough well,
But after some modifications i notice a larger jitter (With my scope)
and i don' t find the reason.
I have several sub vi's use in the two vi.
Is is it the reason for my greater jitter ??
And if yes : have i to set theses subvi to reentrant or else actions ?
Thanks for your help.
Christophe

Hello Christophe,
you are absolute right with your assumption: Having non-reentrant VIs in both, the high-priority and the lower-priority VI is a so-called shared resource. (This term you will also find in the RT documentation.)
A higher-priority VI cannot execute a shared VI as long as a lower-priority VI currently executes this shared VI (This is only true if the shared VI is not reentrant). Making your shared VI(s) reentrant will avoid this and decrease the jitter of your high-priority VI. (Verify that each shared VI is a candidate for a reentrant VI.)

Is it possible to config memory size for a process?

Dear experts,
I would like to control the memory size assigned for a process on Solaris 9. Can i config memory size assigned for process??
Many thanks,
Shun

You can use ulimit/limit to assign a bound on the amount of space that a process and its children can allocate.
I'm not sure if that's what you're asking though.

Is it possible to change network adapter priority in windows 7 by command line?

Ik need to change my users network adapters so that the LAN network adaperts have a higher priority than the WLAN adapters.
I would prefer to do it trouhg a command line so that is can distrubute it with SSCM.
Can annybody help me??

I've found the following Blog article for you:
http://win7settings.blogspot.be/2012/04/how-to-set-network-adapter-priorities.html
From the Command Line
Unfortunately there is no out-of-the-box command line interface for these Advanced settings described above. Luckily, there are two ways to set the priorities from the command line. The more difficult way is to set metrics for each network adapter (using netsh). The much easier way (easier to manage too) is to use nvspbind made by Microsoft. If you set the priorities using nvspbind, the effects can also be seen in the Advanced settings in ncpa.cpl. Here is how you use nvspbind:
Go to http://archive.msdn.microsoft.com/nvspbind and download nvspbind. Extract the nvspbind.exe and copy it to the target machine and run:
nvspbind.exe /++ "Wireless Network Connection" ms_tcpip
nvspbind.exe /++ "Wireless Network Connection" ms_tcpip6
nvspbind.exe /++ "Local Area Connection" ms_tcpip
nvspbind.exe /++ "Local Area Connection" ms_tcpip6
And that's it! You're done.
This will set the priorities (IPv4 and IPv6) to:
1. LAN
2. WLAN
3. WAN (if present)
